Description
Technical field
The invention belongs to wastewater treatments and field of solid waste resource utilization, and in particular to a kind of to be with waste residue source nanoparticle
The method of carrier adsorption separation water body intermediate ion state organic matter.
Background technique
With science and technology and economical propelled at high velocity and development, China's industrial level is also increased substantially, metal waste residue
Yield is also continuously increased.For the statistical research of non-ferrous metal industry, by 2017, the non-ferrous metal industry in China was smelted
About 9,200,000 tons/year of waste residue growth rate, waste residue total amount is about 1.5 hundred million tons.Based on mineralogical property and smelting process, in waste residue
There are a large amount of valuable metals.For example, generating a large amount of copper ashes in Copper making and refining process, there are 40% ~ 55% in copper ashes
FeOx, 25% ~ 40% SiO2, 10% or so Al2O3And the metallic elements such as CaO and a small amount of Cu, Au, Ag.But copper ashes
Structure is complicated, and disseminated grain size is thin, and valuable element therein is difficult to effectively extract, industrially usually by the way of stockpiling
Reason, causes the pollution of environment and the waste of land resource.Aluminium electroloysis slag from delining is permeated the ground water by stockyard bottom stratum,
To cause the pollution of environment.Steel slag is the solid waste discharged in steel mill crude steel smelting process, in steel slag there are 2%~
8% Fe2O3The Al for being 2%~8% with content2O3Deng.In China, the utilization ways of steel slag are more, are mainly used as cement concrete
Admixture, build the road and building materials in terms of, but utilization rate is lower, only 20% or so.It is domestic in terms of the recycling of waste residue
Outer researcher has done a large amount of research.For example, Cao Xing etc. is at " a kind of stable curing continuous processing technique of heavy metal waste slag "
(CN108467236A) it is proposed in and solidifies heavy metal waste slag, carbide slag, heavy metal stabilizer by certain metering ratio, led to
Piping is delivered to specified region and is stored up.The method achieve the reductions of heavy metal waste slag pollutant performance, but also result in
The waste of metal resource.Zhao's companion's fine jade etc. is at " a kind of repairing method of microorganism in the place containing heavy metal waste slag stockpiling "
(CN108856283A) it is proposed in using the waste residue for containing the heavy metal elements such as lead, zinc, cadmium stockpiling place as culture medium, is used
Mixed sulfate reducing bacteria and bacillus subtilis repair soil, can remove polluter.The method achieve waste residues
Resource utilization, but severe reaction conditions, and the period is longer.Liu Abao etc. is in " a kind of cupric, manganese, cobalt, zinc, a nickel huge sum of money
Belong to the processing method of waste residue recycling " propose in (CN108754148A) using sulfate reduction leaching, Extraction electrodeposition mention copper,
Neutralize removal of impurities, vulcanize heavy cobalt, be carbonized the techniques such as heavy manganese, evaporative crystallization, realize non-ferrous metal and extract to recycle and maximize, but
It is that the process is more complicated for the method, energy consumption is high.Therefore, in conjunction with the property of metal waste residue, it would be highly desirable to the economical rationality of development of metallic waste residue
Utilize method.
Waste water intermediate ion state organic matter mainly include have the oxygen such as carboxyl, phenol, enol, alcohol, carbonyl, amine, sulfydryl,
The presence of the aromatic series and lipid organic compound or non-homogeneous mixture of nitrogen and sulphur functional group, ionic state organic matter is living to the mankind
Dynamic and water environment generates negative effect.For example, phenol is the raw material of the industry such as high molecular material, synthetic dyestuffs, medicine, pesticide
One of, due to the extensive use of phenol, pollution is inevitably resulted in, it is a kind of extremely toxic substance, can be carcinogenic, it has been put into
The blacklist of organic pollutant.Xanthic acid group is primarily present in beneficiation wastewater, is had certain toxicity, is contained xanthogen
The butyl xanthic acid of group, which is mainly manifested in the toxicity problem of people and animals, injures nervous system and liver organ, also has to reproductive system
Adverse effect.Containing metallic elements such as Cu, Al, Fe in metal waste residue, bridge formation can be played with waste water intermediate ion state organic matter and is made
With.Therefore, in conjunction with the property of metal waste residue, play the effect of metallic element in waste residue, by metal waste residue be applied in water body from
The removal of sub- state organic matter, not only realizes the resource utilization of metal waste residue, while it is organic to also achieve water body intermediate ion state
The efficiently concentrating and water body purification of object.
